Attempting to equip a weapon, passed value is not a function?

server script

function blaster1(player, blaster)
    if player then
        local clone = blaster:Clone()
        clone.Parent = player.Backpack
    end


end

BlasterEvent.OnServerEvent:Connect(blaster1())

local script that is under a button gui in starter gui

local player = game.Players.LocalPlayer
local leaderstats = player:WaitForChild("leaderstats")
local event = game.ReplicatedStorage.Equips
local weapon = false
local guns = game.ReplicatedStorage.Weapons
local E1 = player.PlayerScripts:WaitForChild("E1")

local co1 = coroutine.create(function()
while wait() do
    if E1.Blaster.Value == true then
        weapon = true
        script.Parent.BackgroundColor3 = Color3.new(0, 255, 0)
        script.Parent.Text = "Equiped"
        script.Parent.Parent.SMG.Visible = false
            script.Parent.Parent.AK.Visible = false
            script.Parent.Parent.Bow.Visible = false

            script.Parent.Parent.Sniper.Visible = false
        else
    end
end

end)

coroutine.resume(co1)
